Research output: Chapter in Book/Report/Conference proceedingConference contribution


We investigate the needs of some massively parallel applications running on distributed-memory parallel computers at Argonne National Laboratory and identify some common paralell I/O operations. For these operations, routines were developed that hide the details of the actual implementation (such as the number of parallel disks) from the application, while providing good performance. An important feature is the ability for the application programmer to sspecify that a file be accessed either as a high-performance parallel file or as a conventional Unix file, simply by changing the value of a parameter on the file open call.
